每当准备水田用种时,许多稻农要到几十公里、甚至几百公里的科研单位、种子公司经销处购买水稻良种。有的人开口就说:“我买最好的(或最贵的、最高产的)新品种。”这种做法考虑的不够全面。大家知道,水田有河水(水库水)灌溉,也有井水灌溉。在选择品种上是有区别的,在河水条件下表现好的品种,也许在井水条件下表现一般,甚至不太好。在河水条件下可以种植晚熟品种,在井水条件下常规栽培就不宜种植晚熟的了。因此,在选购水稻良种时,应主要考虑以下三点: 一看熟期。在我省水稻研究与栽培的实践中,主要推广应用4个熟期的水稻良种,即中早熟(128—131天)、中熟(133—136天)、中晚
Whenever paddy fields are planted for use, many rice farmers have to go to scientific research institutes and seed company distribution shops that purchase dozens of kilometers or even hundreds of kilometers of rice seed. Some people say: “I buy the best (or the most expensive, most productive) new breed.” "This approach is not considered comprehensive enough. As we all know, paddy fields have water (reservoir water) irrigation, but also well water irrigation. There are differences in the choice of species, good performance in river conditions, breeds may well behave under well conditions, not even very good. Under the conditions of the river can be planted late maturing varieties, well-conditioned under well-water cultivation should not be planted late. Therefore, the purchase of rice seed, should mainly consider the following three points: First, look at the maturity. In the practice of rice research and cultivation in our province, four major rice varieties of maturity are mainly popularized, that is, middle-early-maturity (128-131 days), medium-maturity (133-136 days)
